Leviticus 11:11

They shall be even an abomination unto you; ye shall not eat of their flesh, but ye shall have their carcases in abomination.

EXPOSITORY (ENGLISH BIBLE)

Matthew Henry's Concise Commentary

11:1-47 What animals were clean and unclean. - These laws seem to have been intended, 1. As a test of the people's obedience, as Adam was forbidden to eat of the tree of knowledge; and to teach them self-denial, and the government of their appetites. 2. To keep the Israelites distinct from other nations. Many also of these forbidden animals were objects of superstition and idolatry to the heathen. 3. The people were taught to make distinctions between the holy and unholy in their companions and intimate connexions. 4. The law forbad, not only the eating of the unclean beasts, but the touching of them. Those who would be kept from any sin, must be careful to avoid all temptations to it, or coming near it. The exceptions are very minute, and all were designed to call forth constant care and exactness in their obedience; and to teach us to obey. Whilst we enjoy our Christian liberty, and are free from such burdensome observances, we must be careful not to abuse our liberty. For the Lord hath redeemed and called his people, that they may be holy, even as he is holy. We must come out, and be separate from the world; we must leave the company of the ungodly, and all needless connexions with those who are dead in sin; we must be zealous of good works devoted followers of God, and companions of his people.

Barnes' Notes on the Bible

Any fish, either from salt water or fresh, might be eaten if it had both scales and fins. but no other creature that lives in the waters. Shellfish of all kinds, whether mollusks or crustaceans, and cetaceous animals, were therefore prohibited, as well as fish which appear to have no scales, like the eel; probably because they were considered unwholesome, and (under certain circumstances) found to be so.

Jamieson-Fausset-Brown Bible Commentary

9. These shall ye eat … whatsoever hath fins and scales—"The fins and scales are the means by which the excrescences of fish are carried off, the same as in animals by perspiration. I have never known an instance of disease produced by eating such fish; but those that have no fins and scales cause, in hot climates, the most malignant disorders when eaten; in many cases they prove a mortal poison" [Whitlaw].

Matthew Poole's Commentary

An abomination unto you, to wit, for food. This clause is added to show that they were neither abominable in their own nature, nor for the food of other nations; and consequently when the partition-wall between Jews and Gentiles was taken away, these distinctions of meats were to cease. See Ac 10.

Gill's Exposition of the Entire Bible

They shall be even an abomination to you,.... This is repeated again and again, to deter from the eating of such fishes, lest there should be any desire after them:

ye shall not eat of their flesh, here mention is made of the flesh of fishes, as is by the apostle, 1 Corinthians 15:39. Aben Ezra observes, that their wise men say, this is according to the usage of words in those ages:

but you shall have their carcasses in abomination; not only abstain from eating them and touching them, but to express the utmost aversion to them.

Geneva Study Bible

They shall be even an abomination unto you; ye shall not eat of their flesh, but ye shall have their carcasses in abomination.

EXEGETICAL (ORIGINAL LANGUAGES)

Leviticus 11:11

Keil and Delitzsch Biblical Commentary on the Old Testament

(cf. Deuteronomy 14:9 and Deuteronomy 14:10). Of water animals, everything in the water, in seas and brooks, that had fins and scales was edible. Everything else that swarmed in the water was to be an abomination, its flesh was not to be eaten, and its carrion was to be avoided with abhorrence. Consequently, not only were all water animals other than fishes, such as crabs, salamanders, etc., forbidden as unclean; but also fishes without scales, such as eels for example. Numa laid down this law for the Romans: ut pisces qui sqamosi non essent ni pollicerent (sacrificed): Plin. h. n. 32, c. 2, s. 10. In Egypt fishes without scales are still regarded as unwholesome (Lane, Manners and Customs).
